It Also, as the frequency of use of the slide switch increases, the elastic force of the arch weakens and the protrusion as the positioning selection member and the protrusion of the positioning frame push against each other, pushing the rider to the stop position, that is, the recess. Becomes difficult. As a result of the above, the feeling (click feeling) that the slider has selected the selected location becomes worse.

[0012] Therefore, if the stop position is determined at one point as in the prior art, each stop position is surely stopped at the concave portion, and the convex portion other than the stop position is smoothly moved. It becomes difficult to move, and it is possible that it will stop at a position other than the stop position.

Therefore, in order to improve the click feeling, the unevenness of the positioning frame is increased, and the curve of the arch portion is increased so that the protruding portion as the positioning selection member and the protruding portion of the positioning frame are pressed against each other. It may be possible to increase the force, but in order to use this method, it is necessary to make the spacing between the positioning selection points on the positioning frame wide, and the size of the slide switch itself becomes large, so it is a good solution. Not a method. Rather, it is desired to improve the configuration of the positioning frame itself.
